揚雄《太玄》擬準於《易》，錯綜道家之思想與時代的《易》學觀，建構出一套既有承擬，又為新制的推天道明人事之占驗系統。準《易》的實質內容與意義，成為歷來關切之議題。宋代以降，在邵雍的重視與推波助瀾之下，結合《易》說與圖式結構的詮釋方式呈現，也影響日後準《易》圖式化的構制，並為《易》家《易》著所關注者。本文主要概括分析《太玄》擬準《周易》的具體內容，以及宋代以降開啟圖式化發展之重要內涵。首先討論揚雄準《易》的思維內涵，進而從學術發展的視域，探述歷代《太玄》準《易》之詮解取向，以及揚雄《太玄》準《易》之圖式化理解，為《易》家關注的流衍情形，確立其流衍之譜系，乃至學術上的重要意義。

In his book Taixuan, Yang Xiong, based on conventional Yi philosophy, created a new divination system by incorporating features of Daoism and Yi theories in his time. The content and meaning of Yang's innovation has been widely reviewed and provoked much discussion. Among others, in Song Dynasty, Shao Yong praised Yang and greatly promoted Taixuan. He adopted the approach of interpreting Zhouyi and Taixuan by combining Yi and Tu-shi diagrams, which has since had a significant impact on the construction of Yi diagrams and drawn considerable attention from other Yi scholars. The present study aims to analyze Yang's imitation of the structure and content of Zhouyi in his Taixuan and further explain his diagram simulation of Zhouyi; from the angle of academic development, explore different interpretations of Yi with diagrams since Song, and the popularity of Taixuan and philosophers' inclusion and discussion of it in their books; establish potential inheritance and derivation relationships; and offer a brief indication of Yang's role in Yixue history.
